Mountain bike parts

Rear-derailleurs are some of the most important mountain bike parts: They are responsible for moving the chain between gears when the rider shifts. After many miles of vibration, some derailleurs tend to skip gears–which can prove difficult irritating during a strenuous climb.

Besides derailleurs, Shimano makes other quality mountain bike parts, including:
• Hubs
• Chains
• Shift levers
• Gear cassettes
• Service parts

Shift levers are mountain bike parts located on the handlebars; they signal the derailleur to switch between gears. Rapid-fire shifts are located under the brakes, controlled by the thumb and index finger–they have become standard for mountain riding after grip-shifts proved to be inconvenient.
